Magnitude-6.4 quake rocks central Chile

SANTIAGO, Chile 
U.S. monitors say a magnitude-6.4 earthquake has struck just off the shore of central Chile, affecting the same area where last year's much larger earthquake set off a devastating tsunami.

Chile's emergency office says Wednesday's quake was a 6.3 and that no damage to people or buildings has been reported.

The U.S. Geological Survey says this earthquake struck just before 9 a.m. (1300 GMT) and was centered 59 miles (96 kilometers) southwest of Concepcion, the capital of Chile's Bio-Bio region.
